To all whom 'it may concern:

Be it known that I, ELMER G. KNooP, a citizen of the United States, residing at Columbus, in the county of Franklin, State oi Ohio, have invented certain new and useful Improvements in Scarf-Pins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in pins, and it has particular reference to a scarf pin including means for preventing accidental displacement, loss, or theft of the same.

The invention s eciiically comprises a pin shank and a head Formed with fingers to surround the shank, one oi' the fingers being resilient, the shank being form ed with enlargementsto engage the fingers and being capable of sliding movement equal to the distance between the enlargements.

In connection with a device constructed generally as above described, the invention aims as a primary object to provide a novel construction, combination and arrangement of parts, the details of which will appear in the course of the following description, in which reference is had to the accom anying drawings forming a part of this speci cation, like characters of reference designating similar parts throughout the several views, wherein:

Figure 1 is a front elevation of a pin constructed in accordance with the present invention. Fig. 2 is a side elevation thereof. Fig. l3 is an enlarged elevation of the shank. Fig. 4 is an enlarged elevation of the head and its adjuncts. Fig. 5 is an enlarged detailed section showing the manner of inserting the pin in a tie. Fig. 6 is a similar view showing the pin in use.

Referring specifically to the accompanying drawings, the numeral 1 designates the shank and the numeral 2 designates the head. The shank 1 is formed with a pointed lower end 3 and with a pointed upper end 4 adjacent which is a protuberance 5 oi substantial diamond or oval shape and at a distance from the protuberance 5 is a similar protuberance 6, the shank 1 being designed for sliding movement with relation to the head 2, such movement being limited in either direction by the protuberances 5 and 6. At a point approximately central between said protuberances the shank is formed with an annular groove '7, the purpose of which will be eX" plained hereinafter.

The head 2 is constructed of an ornamental base 8 and an attachment secured thereto in any suitable manner such attachment being preferably formed from an integral section of metal and com rising a base portion 9, an upper horizonta projecting finger 10, having a central opening 11, an angular lower portion 12 from which projects a vertical s ring finger 13, terminating in a horizonta inwardly pointing extension 14 having a central opening 15 formed to be alined with the opening 11.

The finger 10 and the extension 14 surround the shank 1 between the protuberances 5 and 6. In use, the pin is inserted in a scarf as shown more particularly in Figs. 5 and 6, by first projecting the pointed end 3 through the scarf and by moving the head to its upward limit until the extension 10 engages the protuberance 5. The spring finger 13 is then pressed inwardly so as to aline its opening 15 with the o ening 11, and the shank 1 is pushed upward y, its pointed end 4 entering the material of the scarf just above the extension 14. Such action is continued until the protuberance 6 impinges the extension 12, it being understood that said extension 12 has an opening 16, through which the shank 1 projects. The spring finger 13 at this time will of its own resiliency spring outwardly and engage the edgp of its o ening 15 in the groove 7, thereby olding t e shank 1 against accidental displacement. The pin is removed by pushing inwardly upon the finger 13 and by sliding'the shank 1 downwardly until its end 4 is removed from the tie, at which time, the shank 1 is then moved in a reverse direction until its end 3 is disengaged from the tie.

A device constructed in accordance with the present invention is simple, inexpensive to manufacture and practical and efficient in use.

From the foregoing description it will be seen that simple and eiiicient means are provided for accomplishing the objects of the invention, but while the elements herein shown and described are well adapted to serve the functions set forth, it is obvious that various minor changes may be made in the proportions, shape and arrangement of the several parts, Without departing from the spirit and scope of the invention as defined in the appended claims.

What is claimed is;

l. A pin of the type set forth, comprising a shank having pointed upper and lower ends, and formed with spaced protuberanoes and a head slidabiy engaged on said shank between said protuberances.

2. A pin of the type set forth7 comprising a shank formed with spaced protuberances, and with a groove between said protuberanoesand a head including a member surrounding said shank between said protuberanoes and a spring iinger formed to engage said groove and to hold said head against movement.

In testimony whereof, I aiX my signature, in presence of two witnesses.

ELMER G. KNooP.
